CHARLES SMITH, OF RGERS, ARKANSAS.

HOOK.

SPECIFICATION forming part of Letters Patent No. 400,5()1, dated April2, 1889.

Application filed December 29k, 1888. Serial No. 294,920. (No model.)

vparts of a harness, and for other analogous purposes; and it consistsin the peculiar construction and combinationl of devices that will bemore fully set forth hereinafter, and particularly pointed out in theclaims.

In the drawings, Figure l is a perspective view of the obverse side of asnap-hook embodying my improvements. Fig. 2 is a similar View of thereverse side of the same, showing the hook in dotted lines, swung toaposition to admit of the disengagement of Fig. 3 is a sectional view ofmy improved snap-hook.

A represents a circular guard-disk, and BY represents the shank whichprojects therefrom, and is provided at its outer end with a transverseslot, C, adapted for the attachment of one end of a strap, in the usualmanner. Said disk or guard and said shank are formed integrally of asingle piece of metal, which may be either cast, wrought, or stamped.The shank B has at its inner end an offset or shoulder, D, whichconnects it with the guard-disk, the said shank being thereby arrangedparallel with but in a different plane from the guard-disk. The latterhas in that portion of its periphery which is under the-shanka'crescent-shaped notch,

y E, the radius of which will in a measure be governed by the size ofthe ring or link F.

G represents a hook, which has its inner end pivoted under the center ofthe guarddisk by means of a bolt, I-I. A washer, I, is interposedbetween the. head of the bolt and the hook, and a nut or washer, K, isscrewed or swaged on the opposite end of the bolt and bears against thecenter of the guard-disk. The point of the hook bears upon the upperside of the guard-disk, and said hook is adapted to be swung to any desired position on the pivotal bolt.

In order to attach the ring or link F to the hook, or to disconnect thesame therefrom, the hook must be swung to a position under the shank Bin order to clear its point of the guard-disk, as illustrated in dottedlines in Figs. 2 and 3.

A snap-hook thus constructed is cheap and simple, is very strong anddurable, and is so arranged that it is almost impossible for the ring orlink to become accidentally detached from the hook, owing to the factthat the latter must be swung to a position under the shank and directlyregistering with the notch in the disk, and to the further fact that thering or link must be swung over the point of the hook at the instantthat the latter is in this position before it can become disengaged.

I am aware of the Patent No. 86,188, granted January 26, 1869, in whichis shown a hook pivoted to a plate, the latter being provided with anotch, so that when the -hook aligns with the notchthe device can bereleased; but in this patent the notch is provided on one side; and,furthermore, the point of the hook does not bear on the plate. In myinvention the notch in the disk is provided at theV inner end, so. thatthere is no possibility of the ring F being detached.

Having thus described my invention, I claiml. The snap-hook comprisingthe circular disk A, having the notch E in one side, the shank B,projecting from the disk and having the offset or shoulder D at itsinner end attached to the disk at the notched portion thereof, wherebythe said shank extends over 'the notch and is in a different plane 'fromthe disk, and the hook G, having its inner end pivoted to the centerofthe disk, the point of the ho'ok being adapted to sweep on and incontact with the disk until it reaches the notch E, substantially asdescribed.

2. The snap-hook comprising the circular disk A and the integral shankB, said disk having the notch E in one side, and said shank having theoffset or shoulder D and being arranged over the notch, and the hook G,having its inner end pivoted under the center of the disk, and havingyits point adapted to sweep on and in contact with the disk until itreaches the notch E, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
